CHAdeMO adapter wait frustration

Ran into this pic which was posted on plug share. Looks like someone already has one. This is from a chademo charger in Gastonia, nc

Sylvain Juteau, founder of the Quebec EV site roulezelectrique, is reporting that the adapter will be on sale in North America next month (January 2015).

Cliffs: A direct response from Jérôme Guillen at the Montreal Store's grand opening: "I'm sure it will be January and you can quote me on it."

The picture in that article also answers the question about it resting on the car :)

Difficult to tell from the pic, but does the adapter rest against the car, or is the weight of the charging cable enough to hold it back? Wouldn't want that giant-ass connector rubbing against my paint.

The picture on the Tesla Store shows that it the Tesla-end plug holds the body of the adapter away from the body of the car--that being said, it seems like its might be applying some meaningful torque to the charging port.

Hi, Mayhemm, if you plug the CHAdeMO adapter roughly, then the charger cable might hit your paint, but if you are careful connecting the cable first to the adapter away from the car, and then connect the adapter to the car, you'll never hit the paint. I've used the adapter a few dozen times but it never happened.

Compatibility is more of an issue I guess. Last week I encountered a new-looking Nissan charger and tried five times, disconnected with errors, and charged only 10kWh. On the next day I got one error with 0kWh, then I was able to charge full 30 minutes. The charger is configured to stop after 30 minutes. I then topped up several more minutes. They charged me for only "one charge".

Have you eventually succeeded to charge with all chademos?

I think this speaks to the fact that the "Chademo-standard" in fact is not very well standardized. There have been reports i Norway of the new Kia Soul EV not being able to charge on some Chademo-charges, while working well with others. The Chademo protocol/signaling seems overcomplicated.

Yes, and that is a little worrying. I am sure they have considered that in design, but still, when I look at it, I feel uncomfortable! Looks like a slight nudge to the silver connection (by a passer by, for example) would translate to a lot of pressure on the charging port.
 
Unfortunately no. Approximately one out of four chargers has not been compatible with Tesla Model S. In addition, some chargers work, but derated to 107A (should be 125A if 50kW). I'm trying to share these info with Japanese owners and Tesla.

I think it is 107A because of the limitation of the battery in regards to voltage ( I think it is 375v). 44kW will probably be the highest you will get from CHAdeMO with the Tesla.

125Ax400volt = 50kW
107Ax400volt = 43kW so this is very good

I think it's the other way around.

Charging happens at somewhere around 340V when the battery is empty and goes up to 380V.

340V * 125A = 42.5kW

The current (125A) will be the limit due to the "low" voltage.

definitelly, it should be 125A if CHAdeMO station is capable of that. Don't forget that SuperChargers are capable of 360A :)
 
Even "limited" it would still provide around three times the charge rate of the most powerful level 2 EVSEs.
I'd take it in a heartbeat; even put up with that freakshow of an adapter.

Curbing my enthusiasm are continued reports of malfunction of Chademos, specifically in the Ft Collins CO area. The new one at the Science Museum is an 8 ft monster but nonetheless a *single* unit. And it has been reported 'down' often on PlugShare. But PS reports another Chademo in FC and a 3rd nearby in Longmont, the latter unfortunately seems in need of complete replacement. The other FC unit is like the new one with off and on again useability. So overall there might be a collective reliability here such that at least one might be functional on any particular day. I just might be jumping on this bandwagon after all.

Yes, as you note, the most powerful L2 AC EVSE correspond to the Sun Country Highway deployment of 80A L2 EVSE across Canada.
80A * 220V (average, some more, some less) = ~17kW

BUT

There are thousands of these, and they JUST WORK (caps on purpose).
I've monitored the three local DCQC sites in Toronto area, and there are constant problems with compatibility and availability...
